The Relationship Between Laboratory Parameters and Coronary Slow Flow

<b>Background/Objectives</b>: One of the most prevalent reasons for attending the emergency department (ED) is chest pain. There are many causes of its etiology. Recent studies indicate that coronary slow flow should be considered not only an angiographic phenomenon but also a clinical syndrome. In our study, we aimed to identify laboratory parameters indicative of coronary slow flow. <b>Methods</b>: Patients who presented to the Emergency Department of Balikesir University Hospital with chest pain and underwent coronary angiography between 2019 and 2023 were evaluated. A group of 107 patients with primary coronary slow flow was included as the patient group, while 108 patients without any pathology were included as the control group. Demographic, laboratory, clinical, and angiographic parameters were compared between the two groups to determine the predictors of coronary slow flow. <b>Results</b>: In our study, RCA dominance was detected in the control group, while Cx dominance was detected in our patient group (<i>p</i> < 0.001). CRP and the CRP/albumin ratio were observed to be higher in the patient group (<i>p</i> < 0.001). <b>Conclusions</b>: The inflammatory markers CRP and CRP/albumin ratio were found to be statistically significantly higher in the patient group. These parameters can be used to predict coronary slow flow in the emergency department.
